摘要： A system and method for manufacturing a space-based component in space. The method includes collecting and capturing space debris directly from and suspended in space, heating the collected space debris using solar radiation in a manner that separately and independently melts different constituent elements and compounds in the space debris, collecting the different constituent elements and compounds as they are being separately melted, storing the elements and compounds in a molten, solid or vapor form, and fabricating the space-based component using the stored elements and compounds.

摘要： Novel methods for the production of iron, silicon, and magnesium metal from extraterrestrial and terrestrial resources are described. The methods employ processing steps including metal oxide reduction using carbon monoxide, carbon, hydrogen, and methane. Methods to prepare, regenerate, and recycle reductants to minimize mining and purchase of fresh materials and to minimize carbon emissions are included.

摘要： This invention is a process for producing foamed material in space comprising the steps of: rotating the material to simulate the force of gravity; heating the rotating material until it is molten; extruding the rotating, molten material; injecting gas into the extruded, rotating, molten material to produce molten foamed material; allowing the molten foamed material to cool to below melting temperature to produce the foamed material. The surface of the extruded foam may be heated to above melting temperature and allowed to cool to below melting temperature. The extruded foam may also be cut to predetermined length. The starting material may be metal or glass. Heating may be accomplished by electrical heating elements or by solar heating.

摘要： The disclosed invention resolves the problem of manufacturing three-dimensional objects by stacking two-dimensional layers of material in the third direction z. Described are a machine and a method for additive manufacturing of three-dimensional objects in which a predetermined final object is fabricated using the steps of the printing process (100) of individual curved three-dimensional print volumes (1, 2, 3 . . . Z) in a sequence (51). Powdered material (102) is melted in a melting volume (280) which is inside an intersection volume (28) and in which the energy exerted by at least two particle clusters (160,170) emitted from at least two spatially positioned sources (11, 12) of particles with mass adds up and exceeds the threshold required for melting of the powdered material. Machine and method according to the disclosed invention enable the fabrication in multiple different printing directions simultaneously.
